@simonis Can you create a bug/ticket for that secondary crash with repro info? That sounds like a real bug. (If not all necessary info/files are readily available, maybe you can collect them in the next occurrence.) Depending on how it goes with Serial, we can probably do sth similar in other GCs (e.g. Parallel).

What do you think?
